Most houses in Sherwood went up around 1997, almost two decades newer than the 1978 median build year across the rest of the service area we cover out of Happy Valley. That gap matters more than it sounds like it should. A door built in 1997 already came with photo-eye safety sensors as standard, galvanized torsion springs rated for a set number of cycles, and steel rollers that were considered good enough for a subdivision build - not the heavier-duty stuff a contractor might spec on a custom house. Torsion springs on a daily-use door generally run out of cycles somewhere in the 7 to 12 year range, so if this house still has its original spring, it would be unusual - not impossible, but unusual. What's more likely still original: the rollers, the hinges, and the track.
